This weekend is International Dawn Chorus Day. The first Sunday in May has become a good moment to stop and enjoy the increasing cacophony of natural sounds as Spring settles in.

Depending on your feelings, this can be little more than a half-noticed thing on a warm night with the window left open. Or it can be something worth waking up early for – to seek out some nearby woodland or farmland and really get amongst it.

If you want to go another step further, you could even listen to Soundcamp’s live audio show, a 24-hour broadcast called Reveil aiming to capture the chorus as it rolls across the face of the globe. There are also various Soundcamps taking place: literally campsites for like minded folks to turn up and listen in to the dawn chorus as it unfolds.

You can even take part in the audio feed by streaming your local environment via microphone and internet connection, and allowing the main feed’s curators to bring in your sounds. There’s a lot more information on how to do that, and the project in general, here.

The great thing is that this won’t sound the same everywhere – for some it’ll be a familiar twittering, but elsewhere it might be captured by hydrophones bobbing in the ocean waves.

Starting on the morning of Saturday 5 May just before daybreak in Rotherhithe near the Greenwich Meridian, the Reveil broadcast will pick up these feeds one by one, tracking the sunrise west from microphone to microphone, following the wave of intensified sound that loops the earth every 24 hours at first light.

In 2018 Reveil features new streams from the UNESCO Monarch butterfly Biosphere Reserve at Cerro Pelón, State of México, the Noosa Biosphere Reserve in Queensland, Australia, a gull colony on South Walney Island, Cumbria, UK

The broadcast will run from 5am on Saturday morning until 6am on Sunday morning.

Whatever the source of the audio, you’ll be able to tune in online here, or in London via Resonance FM, who will play snippets including 5am-6am and 10.30pm-12am on Saturday, and Resonance Extra, which will be playing the whole thing live. Resonance Extra was recently added to the DAB Trial London multiplex.
